CORNER FASTENING FOR BEDSTEADS.

Application filed. March 18, 1922. 7 Serial No. 544,775.

To all whom it may concern:

Be it known that I, Mounts LowY, a citizen of the United States. and resident of the city of New York, in the county of Kings and State of New York, have invented certa-in new and useful Improvements in Corner Fastenings for Bedsteads, of which the following is a specification. Y

The present invention relates to improvements in corner-fastenings for bedsteads and has for its main object to provide a simple, eflicient and durable device of this type, to which the bed-bottom supporting angle bar may be reversibly secured, so as to adapt it to ordinary spring mattresses and also to box springs.

Another object of the invention is to produce a corner-fastening of the type mentioned, which permits of a convenient assembling of the bed and of a taking down of the same by inexperienced operators with but little time and energy and without the aid of tools.

A further object of the invention is to so construct the corner-fastening that the bed bottom supporting member may be clamped thereto or released therefrom by an element that is permanently attached to the cornerfastening. there being thus no chance of losing or misplacing the clamping member.

lVith these and other other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the 'combination,'arra-ngement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and pro-- portion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which 2-- Figure 1 is a plan view of a cornerfastening, constructed in accordance with the present invention, in position upon the corner-post of a bedstead, the bed-bottom supporting angle bar being shown positioned to receive an ordinary spring mattress; Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is a section taken on line 3-3 of Fig. 1; and Fig. 4 is a section similar to the one shown in Fig. 3, showing the bed-bottom supporting angle bar positioned to receive a box spring.

In the drawings, the numeral 10 indicates the corner-post of a bedstead, to which the corner-fastening is to be attached. In the case illustrated this post is of rectangular cross-section, although this is'not essential. The corner-fastening includes a bracket-like hollow rectangular shell'll, for instance in the form of a casting. This shell includes an end wall 12, a top wall 13, an outer-side wall 14 and a bottom 15. The end wall projects above the top wall 13, as shown at 16, and also below the bottom 15, as shown at 17; i The said end wall abuts against the inner face of the corner-post, the shell being secured to the latter by screw bolts 18, passing through the projections 16 and 17 into the corner-post. The top wall 13, side wall 14 and bottom 15 extend in planes at right angles to the end wall 12, that is to say longitudinally of the bedstead. Opposite the outer side wall 14 the shell is'open, for a purpose hereinafter to be described. The width of the top wall 13 and bottom 15 corresponds to the distance between the said elements, so that the bed-bottom supporting side rail 19, which is made in the form of an angle bar, may be inserted into the shell in two positions. In one of these positions, shown in Figs. 1 to 3, inclusive, of the drawings, the flange 20 of the angle bar constitutes the horizontal flange. 'The other "flange, denoted by the numeral 21. being disposed vertically and below the flange 20.. When so inserted, the flange 2O abuts against the inner face of the top wall of the shell and the flange 21 against the inner face of the side wall thereof. In the other position, shown in Fig. 4 of the drawings, the flange 20 forms the vertical flange of the angle bar and the flange 21 the horizontal flange. In this last-named position, the flange 20 abuts against the inner face of the side wall 14 of the shell and the flange 21 rests upon the bottom 15 of the same.

For clamping the side rail to the shell, there is a lever 22 pivoted to the shell, the pivot being in the form of a rivet 22, that extends through sidewardly extending lugs 23 and 24 on the top wall 13 and bottom 15, respectively, said lugs projecting beyond the free edges of the said top wall and bottom. The lever extends horizontally and ill) transversely of the bedstead, it being provided within the shell with a cam 25, having a side cam face 26 adapted to co-operate with the side wall 14 of the shell. The lever is furthermore provided with an upper cam face 27 and a lower cam face 28, the upper cam face being adapted to co-operate with the top wall 13 and the lower cam face with the bottom 15 of the shell. The lever extends a considerable distance beyond the shell, it having a handle portion 29, by the aid of which the cam may be manually actuated.

The two shells 11 on the corner-posts, forming an end member of-a bedstead, may be connected in any suitable manner, for instance by an angle iron 30, which is fastened by rivets 31,01 otherwise, to lugs 32, the latter being, preferably, made integral with the top walls 13 of the two shells.

The operationof the corner-fastening is as follows: If the bedstead is to be provided with an ordinary spring mattress, the angle bars 19 are inserted into the shells in the manner indicated in Figs. 1 to 3, inclusive, of the drawings, in which the flanges 20 of said bars are disposed horizontally in contact with the top walls 13 of the shells."

In order to permit of such insertion, the cam lever must be shifted from the position shownin full lines in Fig. 1 of the drawings into the position shown in dotted lines in the said figure, so as to bring'its side cam face 26 to a distance from the side wall 11 of the shell sufficient to permit of convenient insertion of the angle bar. After the angle bar has been put into place, the lever is shifted into the position shown in full lines in Fig. 1 of the drawings, whereby. its side cam face 26 binds the vertical flange 21 against the side wall of the shell and its upper cam face 27 clamps the horizontal flange 20 against the top wall13 of the shell. The angle bar may be conveniently disengaged from the shellby moving the lever 22 into the position shown in dotted lines in Fig. 1 of the drawings. 1

If it is desired to use a box spring on the bedstead, the angle-bar must be reversed,

that is to say it must be brought into the position shown in Fig. 4: of the drawings, in which its flange 20 extends vertically, it being in abutment with the side wall 141 of the shell, the flange 21 resting on the bottom 15. The lever is then forced to clamping position, whereby its side cam face binds the flange 20 against the side wall 1 1, the flange 21 being clamped against the bottom 15 of the shell by the lower cam face 28 on the cam.

What I claim is 1. In a corner-fastening for bedsteads, the combination with a corner-post, of a hollow rectangular shell fastened thereto, an anglebar ofthe bed-bottom supporting frame capable of'being reversibly extended into said shell, and a cam lever oscillatably mounted upon said shell for clamping said angle-bar to said shell, said cam lever having a cam face exerting pressure directly upon the vertical flange of said angle-bar in either position of the latter, said cam lever having furthermore two oppositely disposed cam faces coacting with oppositely disposed portions of said shell.

2. In a corner-fastening for bedsteads, the combination with a corner-post, of a hollow rectangular shell fastened thereto, an anglebar of the-bedbottom supporting frame capable of being reversibly extended into said shell, and a cam'lever oscillatably mounted upon said shell for clamping said angle-bar to said shell, said cam lever having a cam face exerting pressure directly upon the vertical flange of said angle-bar in either position of the latter, saidcam le- ,ver comprising furthermore two oppositely disposed cam faces, one of the last-men, tioned cam faces exerting pressure directly upon the horizontal flange of the anglebar when extending uppermost and the other face upon the horizontal flange of said angle-bar when extending lowermost.
